The new 10-speed Dura-Ace® chain is lighter by an astonishing 24g, yet maintains the same durability as the 9-speed predecessor. The chain also adds a new fluid-smooth feel to the performance of the overall system. The rollers are the same width as 9-speed, insuring the important strength and durability.
Weight reduction and the narrower 10-speed profile were achieved by minimizing the contour of the side plates. The super-flush surface of the new plates glides more smoothly across the entire cogset, netting a lighter, smoother, and yet remarkably more durable drive train.
Rated 5 out of 5 by Anonymous Excellent chain.
Having used these chains for years with best results only. I do not use connector pins, replacing it with SRAM PowerLocks ab origin. The results are fine: chain shifts smoothly (much better, than Shimano CN-7900) and costs modestly. The pruduct with best price/quality ratio! Would recommend it to anyone.

Avoid!! These chains are uverpriced tat, waste of £35, faulty link, snapped twice since, All within a month of buying. Has caused me no end of trouble. Having spoken to many people about this problem, the consensus is do not use shimanio chain, apparently a long history of chain problems.
